31. They can also form Zintl phases ( half-metallic compounds formed between highly electronegative metals or metalloids ). 32. Oxygen is more electronegative than carbon, thus the hydrogens alpha to ethers are more acidic than in simple hydrocarbons. 33. The atomic orbital energy correlates with electronegativity as more electronegative atoms hold their electrons more tightly, lowering their energies. 34. One reason is this : oxygen is less electronegative than fluorine, so it holds onto its electrons less tightly. 35. Specifically, the use of more electronegative alkali metals or solvents less amenable to cation solvation generates the desired effect. 36. The sulfur hexaflouride gas ( SF 6 ) is an electronegative gas and has a strong tendency to absorb free electrons. 37. A hydrogen atom attached to a relatively electronegative atom will play the role of the hydrogen bond " donor ". 38. The bonds between even the most electronegative / electropositive pairs such as those in caesium fluoride exhibit a small degree of covalency. 39. For example, chemists often choose to look at a small space surrounding the electronegative , its electrons are partially drawn away. 40. The AC fault current is interrupted at current zero by the highly electronegative SF6 ions absorbing free electrons from the decaying plasma.
